Abstract
Selon une technique cryogénique de récupération d'éthène à partir d'un mélange gazeux contenant du méthane, de l'éthane et de l'éthène, ou fait passer le mélange gazeux dans un train de refroidissement brusque comportant une série d'unités d'échange du type déflegmateur afin de condenser du liquide riche en éthène et en éthane, tout en séparant une majeure partie de méthane et de gaz plus léger. Un déméthaniseur multizone élimine le méthane condensé de la fraction de C2 afin de produire de manière économique un produit pur.
